Patented Dec. 5, 1939 UNITED STATES 2,182,743 'ENGINE STAND Louis OlergL Des Moines ilowa; .Henry Clergy administrator of Louis Clergy, deceased Application November 23, 1936, Seria1*N0.'112,'319

2 Claims.

' about two axesso that the operator may'have' accessibility to any part'of the engine needing repair, without having to reset the engine on its stand, and furthermore to provide means whereby the engine may be easily and quickly adjusted to any desired position, and at the same time rigidly support the engine against accidentally falling to the floor.

A further object of my invention is to provide, in a stand of the type --above described, 'improved means for mounting-an engine whereb-yit maybe tilted about ahorizontal axis, and in connection therewith improvedmeans for tilting said mounting means and atthe same time provide means whereby it may be easily and quickly locked in the desired tilted positions.

A further object is to provide, in a stand of the type above described, improved means for portably supporting the stand where it may be easily moved from one position to another over the floor, and in connection therewith meansfor locking. the stand against movement, when so desired.

.My'invention consists in the construction, arrangement and combination of thevarious parts 5; of the device, whereby theobjects contemplated are attained; as hereinafter more fully set forth, pointed out in my claims, and illustrated in the accompanying drawing, in which:

Figure 1 is a, side elevation of my'improved stand.

Figure 2 is a plan view of the same.

Figure 4 is a detail sectional view taken on the line l4 of Figure 3, a portion of one end of the supporting base being broken away.

Figure 5 is a detail sectional view taken on the line 5-5 of Figure 2.

Figure 6 is an enlarged detail sectional view taken on the line 6-6 of Figure 2.

My improved stand comprises a supporting frame l0 formed of a pair of parallel angle irons H, connected by means of cross rods [2. Secured to the central portion of each member II is an upright angle iron l3, having its upper end connected to the upper end of a brace M, the

o1. cal-189).

lower end of said brace being connected toithe outer end of one of' the bars l2. "The members l3 are connected by crossbrace members 15-, thus providing means whereby the upper ends'of the members 13 are rigidly supported to the 5 members it and spaced apart to receive-between them what- I shall term the-table' [6. The table i6 is secured" to the-members l3 by meansof pivots ll, said pivots being located-"between'the ends of the 'members I6 so-that 'the'table-is 10 partially balanced-and free-t0 swing from the horizontal position shown-in Figure 1, to aminclinedposition as illustrated in Figure 4.

Thetable comprises a-pair-of parallel angle bars is having their free ends connected to 15 cross bars i9, the bars i 9 being supported on top of the ends cf.:the memberslfi. Thelongor front end of the table-l6 is pivota'lly' connected to the upper-ends of a pair of rack bars 20, the lower ends-of-saidrack bars being slidably and g0 telescopically mounted in tubular brace members-2l pivotally mounted on the front bar" l2.

Fixed to the inner side of the upper end of each of the members 2| isa bracket 22 for supporting a shaft -:23, said shaft carryingpinions 25 24 ada-pted. to mesh with theteethof the rack bar 20 in amanner as clearly illustrated in Figure l, the teeth ofthe pinion 24 entering the tube 2|. through a notch.25. By this arrangement:it willbe seen'thatzif the shaft 23 isro- 30 tated, then the rack bar .20 will move .into or out .ofuthetubularmember 2|, causing the table [6 to be tilted. The bars .20 maybelocked in any desired adjusted position by ,means of a hand actuated screw 26 mountedin a suitable bearing. 2"! carried by the upper ends of the members ,2! .and adapted'zto engage thegouter surface of thebarifl;

.,For rotating theshaft 23 I have:provided on one end of the said shaft a gear v28 :adapted to 40 meshgwith' a pinionngear 29 carried bytawstub shaft 30, ,said stub shaft. 13 0 being: rotatably; supported in a bearing 3| carried by one of the members 2|, as illustrated in Figure 3, the outer end of the shaft 30 being provided with a crank 32 by means of which the pinion 29 may be rotated and, in turn, the gear 28, causing the shaft 23 to be rotated. A gear housing 33 is supported by the shafts 23 and 30.

Supported on the members I8 and the table 50 I6 I have provided four. upwardly extending shafts 34, each of which is provided with a grooved roller 35, said rollers being so arranged as that an annular support 36 may be carried in the grooves of said rollers and free to rotate 55 the cross members I!) so that the said members l9 serve to support a portion of the weight of the engine when the table is in a horizontal position, and when the table is in a vertical position the weight is carried by the lower rollers 35. By this arrangement it will be seen that if the table is in a horizontal position, then the engine may be rotated about a vertical axis. If a commercial type of airplane engine is supported thereon, T

in which the cylinders are usually mounted in radial manner, then the cylinders will be supported in a common horizontal plane. It will readily be seen that any of the cylinders may be brought to position in front of the operator standing at one side of the frame, by simply rotating the support 36. Or, if so desired, the table l6 may be tilted and the engine rotated about a horizontal axis.

For locking the member 36 against rotation I have provided in one of the members [9 a threaded shaft 38 mounted in an opening 39 formed in the member I9, having its upper end provided with a head 40, the periphery of said head having a notch 4| for receiving one edge of the member 36. A screw-threaded sleeve 42 is carried by the lower end of the shaft 38, having a hand wheel 43 by means of which the sleeve may be easily rotated to force the flange 44 of the head 46 against the member 36, in turn forcing the member 36 against the member Hi.

In order that the stand may be easily moved from one position to another I have mounted one end of the stand on rollers 45, carried by brackets 46 fixed to the members II. The opposite ends of the members II are carried by swiveled casters 4'! so that the stand may be easily steered when so desired. However, sometimes it is desired to fix the stand against free movement.

To accomplish this I have provided in each of the horizontal flanges of the members ll, downwardly extending brackets 48, having their upper ends screw-threaded and extended through openings 49 in said members II, the upper ends being provided with a lock nut 50 for securing the member 48 in position. The member 48 is provided with a recess 5| and a hole 52 in its lower end. A shaft 53 is slidably mounted in the hole 52 and upwardly through the recess 5|, having its upper end provided with a head 54 for engaging the upper end of a spring 55 carried in the recess 5|.

Rotatably supported in the vertical flanges of 2,182,743 I, Y i

the members II is a shaft 56 having at each end a cam 51 designed to engage corresponding heads 54 in such a manner that if the shaft 56 were rocked, the shaft 53 will be lowered until its lower end engages the floor, after which further rotation of the shaft 56 and the earns 51 will lift the corresponding ends of the members II and, in turn, lift the casters 4'! from the floor, so that the entire weight of the corresponding end of the standard will rest on the members 53, thus providing means whereby the stand will be fixed against easy movement on the floor. Inasmuch as the rollers 45 are not swivelly mounted, the corresponding end of the stand will also be fixed against lateral movement, while the members 53 will support the stand against longitudinal movement.

In the drawing I have described and illustrated one means for elevating and lowering the corresponding end of the table l6. It will readily be seen that various devices may be devised for tilting said table about a horizontal axis without departing from the spirit of my invention.

Thus it will be seen I have provided a stand upon which an airplane engine or numerous other types of engines or devices may be mounted for repair, and when so mounted the engine or device may be supported to rotate freely about a vertical axis,or, if so desired, may be swung to position where it may be rotated freely about a horizontal axis, and in connection therewith means for easily and quickly locking the device.

and the tiltable supporting elements in their various adjusted positions; and, further in connection with a stand of the type above described, means whereby the stand may be easily moved from one position to another over the floor or whereby it may be easily and quickly locked against free movement.

I claim as my invention:

1. An engine stand comprising a supporting frame, a table pivoted to the upper end of said frame to swing about a horizontal axis, an annular engine base, a series of grooved rollers carried by said table for receiving and supporting the periphery of said engine base to permit said base to rotate about an axis perpendicular to said table, means for locking said annular base against rotation, and means for tilting said table.

2. An engine stand comprising a supporting frame, a. table pivoted to the upper end of said frame to swing about a horizontal axis, an annular engine base having a series of holes for receiving bolts by means of which an engine may be secured to said base, a series of grooved rollers carried by said table for receiving and supporting the periphery of said engine base to permit said base to rotate about an axis perpendicular to said table, means for locking said annular base against rotation, and means for tilting said table.
